I installed an AMD RX550 based card last year. It required updates to the kernel, firmware, X driver, and Mesa, which are all available in stretch-backports. > Old ATI/AMD GPUs can use the radeon driver stack, which is also open > source (except for firmware) and comparable to Intel integrated GPUs > (generally faster and more featureful for hardware of equivalent age). > > I think there might be some intermediate models that are too new for > radeon but too old for amdgpu; if they exist, those will be stuck with > the proprietary fglrx driver, which as far as I can tell is like the > NVidia proprietary driver, but worse. fglrx is no longer supported by > Debian contrib/non-free. I'm not aware of any gap. In fact, at the kernel level, there is some overlap where the newest models supported by radeon are also supported (on an opt-in basis) by amdgpu. The proprietary AMD graphics stack now depends on the amdgpu kernel driver rather than replacing it.
